small vacum hose location
 

hi all im just doing a load of little jobs to the impreza and also im bining the boost controller and going back to my 3 port there is one pipe i have no idea on where its ment to connect being the pipe from the turbo housing where do i connect it to ? thanks

Top nipple of Boost Control Solenoid (BSC) goes to turbo outlet nipple
Middle BCS nipple to Actuator
Bottom BCS nipple to free air or into intake pipe expansion box (nipple is normally broken if the box has been removed at any point). This bottom hose must have a 2mm brass restrictor inside or you may overboost.
